On May 4, a food worker who made uncooked sandwiches at a fast-food restaurant in Juneau, Alaska, developed gastroenteritis. He was allowed to remain at work, but told not to handle food. He sought medical attention on May 8 when he became jaundiced. Initially his blood work showed no evidence of acute hepatitis A. However when the blood work was repeated on May 18, the tests then showed evidence of hepatitis A infection. Because two weeks had lapsed between the food worker's onset of illness and confirmation of the infection, immune globulin was not offered as prevention to other food workers or to patrons. Eleven illnesses resulted with onsets between June 1 and 11.
